Description

Technical Field

[0001] The invention relates to the technical field of powder filling bowls, and in particular to an inductive automatic material spreading mechanism for powder filling bowls. Background Art

[0002] Powder packing is a process of loading powder materials into saggers. Powder packing technology is widely used in the production of various powder materials that require high-temperature sintering, such as lithium-ion battery positive electrode materials, rare earth materials, etc.

[0003] Automatic spreading is an automation technology, which is mainly used to load powder materials evenly into the sagger to ensure the quality and efficiency of sintering or other processing processes. In the existing technology, the weight of the material in the sagger is detected by a metering device, and the metering hopper puts the weighed material into the spreading structure, and then the spreading structure evenly spreads the material into the sagger. After completing the filling of a single sagger, the sagger is delivered in an orderly manner by roller conveying, realizing the continuous filling of batch materials.

[0004] However, the material spreading structure of the prior art lacks a real-time monitoring and feedback mechanism for the position of the sagger. The material spreading device cannot dynamically adjust the material spreading position and method according to the actual position of the sagger. When the position of the sagger deviates, if the material spreading structure is still controlled to move and operate according to the set program, the material spreading device will not be able to accurately align with the predetermined position of the sagger, resulting in uneven distribution of powder materials in the sagger. This uneven distribution will affect the quality and efficiency of the subsequent sintering process, and the material spreading device may spread part of the material outside the sagger, resulting in material waste, which not only increases production costs, but also may pollute the production environment.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] See also Figure 1-7 The present invention provides a technical solution: an inductive automatic spreading mechanism for powder bowls, comprising an equipment frame 1, a wire body 34 installed on the equipment frame 1, and a bowl body 35 placed on the wire body 34, the equipment frame 1 is equipped with a mounting frame 2, and an X-direction driving mechanism 32 for controlling the movement of the mounting frame 2, the mounting frame 2 is equipped with a support frame 3, and a Y-direction driving mechanism 33 for controlling the movement of the support frame 3, the support frame 3 is also equipped with a cylinder 30, the output end of the cylinder 30 is equipped with a probe type contact sensor 31, the outer end of the spreading hopper 4 is equipped with a vibrator 27, and the vibrator 27 is equipped with an air pipe joint 28 and a muffler 29.

[0022] The equipment frame 1 serves as the supporting frame of the entire mechanism, the wire body 34 is installed on the equipment frame 1, and the bowl body 35 is placed on the wire body 34. The wire body 34 is responsible for conveying the bowl body 35 to the material spreading station. The wire body 34 is a prior art, and usually adopts a roller conveyor or a belt conveyor mechanism. The roller conveyor mechanism is composed of a plurality of conveying rollers and a driving mechanism, which can realize the smooth conveying of the sagger. The belt conveyor mechanism conveys the sagger from one station to another through a conveyor belt.

[0023] The X-direction driving mechanism 32 controls the mounting frame 2 to move along the X-axis, and the supporting frame 3 is mounted on the mounting frame 2. The Y-direction driving mechanism 33 controls the supporting frame 3 to move along the Y-axis. Through the driving mechanisms in the X and Y directions, the material spreading device can be accurately positioned on the horizontal plane, and the powder can be evenly spread into the bowl 35.

[0024] The X-direction driving mechanism 32 and the Y-direction driving mechanism 33 use existing linear motors. The travel and flexible layout characteristics of the linear motors enable the spreading device to adapt to bowls 35 of different specifications and shapes, as well as different spreading process requirements, thereby enhancing the versatility and adaptability of the equipment.

[0025] The function of the vibrator 27 is to vibrate the powder material in the scattering hopper 4, thereby promoting the flow and uniform scattering of the material. The air pipe joint 28 and the muffler 29 are respectively used to connect the air source and reduce the noise generated by the vibrator 27 when working.

[0026] When the sensor contacts the bowl 35, the existence and position of the bowl 35 can be detected. The application of this sensor enables the material spreading device to monitor the position of the bowl 35 in real time. The cylinder 30 acts as a driving element, and drives the probe-type contact sensor 31 to detect the position through its telescopic movement. It has the advantages of simple structure, fast response speed, high control accuracy, etc., and can meet the needs of the material spreading device for rapid positioning and precise control.

[0027] The metering mechanism puts the weighed material into the spreading hopper 4, the cylinder 30 extends the probe contact sensor 31 into the bowl 35, and the X-direction drive mechanism 32 drives the support frame 3 to move along the X direction. When the probe contact sensor 31 hits the wall on the other side of the bowl 35, the probe contact sensor 31 feeds back the signal to the PLC (control system) to ensure that the spreading device is aligned with the bowl 35 to avoid inaccurate spreading caused by the position deviation of the bowl 35. Then the cylinder 30 contracts to retract the probe contact sensor 31. The spreading hopper 4 will move according to the set trajectory under the action of the X-direction drive mechanism 32 and the Y-direction drive mechanism 33 to achieve uniform filling of the material. After completing the material spreading, the cylinder 30 extends again, and the probe contact sensor 31 extends into the bowl 35. This precise trajectory control can make the material more evenly distributed in the bowl 35, improve the quality and consistency of powder filling, and meet the requirements of the production process for material spreading accuracy.

[0028] When the wire body 34 continuously pushes the two bowl bodies 35 to move, the wall of the bowl body 35 will hit the probe contact sensor 31 twice in succession, and the probe contact sensor 31 will give two signals to the PLC (control system). The control system responds quickly and adjusts the state of the spreading device in time. After the metering mechanism puts the weighed material into the spreading hopper 4 again, a new round of bowl loading operation is carried out. This rapid response and continuous operation capabilities enable the production line to operate efficiently and stably to meet the needs of large-scale production.

[0029] A material spreading hopper 4 is installed on the support frame 3 through an elastic mounting structure 5. A material spreading nozzle 6 is arranged at the bottom of the material spreading hopper 4. A docking frame 7 is fixedly arranged at the end of the material spreading nozzle 6 opposite to the material spreading hopper 4. The two docking frames 7 are locked by bolts. A rotating frame 8 is rotatably connected in the docking frame 7. A driving member for controlling the swing of the rotating frame 8 is arranged on the material spreading nozzle 6.

[0030] When the vibrator 27 is started, the elastic mounting structure 5 can absorb and buffer the vibration and impact generated during the material spreading process, protect the material spreading hopper 4 and the support frame 3, extend the service life of the equipment, and also help reduce the noise during material spreading.

[0031] The elastic mounting structure 5 includes a spring, which is supported between the support frame 3 and the hopper 4, and has a non-metallic gasket to prevent the metal friction from generating magnetic substances during vibration. The lengthened screw passes through the mounting holes of the support frame 3, the spring and the hopper 4, and is tightened by the anti-loosening nut. The anti-loosening nut is padded with a double-stacked self-locking gasket to prevent the parts from falling off due to vibration.

[0032] The sliding frame 11 is slidably linked in the docking frame 7, and a groove 1101 is formed in the sliding frame 11 for laying the screen 13. A clamping structure for fixing the screen 13 is arranged on the sliding frame 11, and a limiter is arranged on the outer side of the docking frame 7 to limit the relative movement of the sliding frame 11.

[0033] When in use, the screen 13 of suitable mesh size can be selected and cut and installed according to the particle size of the material to reduce the residual material, and the material can be evenly sprinkled from the holes of the screen 13 by vibrating the vibrator 27. The vibration frequency amplitude is controlled by the air source pressure flow rate to achieve the purpose of adjusting the material feeding speed. The screen 13 is used to remove some large particles of impurities or agglomerates mixed in the powder material. The screen 13 can intercept particles larger than its aperture and allow qualified materials smaller than the aperture to pass through the screen holes, thereby achieving material screening and impurity removal.

[0034] After a period of material loading, the accumulation of impurities on the screen 13 will affect the material feeding speed. At this time, the driving member controls the rotating frame 8 to swing back and forth, so that the impurities trapped on the screen 13 are loosened and fall off. In this way, the impurities on the screen 13 can be effectively removed, the impurities are prevented from clogging the sieve holes, the screening performance of the screen 13 is restored, and the qualified materials can be ensured to pass through the screen 13 smoothly, and the normal material feeding speed is maintained. And the impurities on the screen 13 can be cleaned up in time, which can reduce the wear and corrosion of the impurities on the screen 13 and prevent the screen 13 from being damaged due to long-term blockage. This helps to extend the service life of the screen 13 and reduce the maintenance cost and replacement frequency of the equipment.

[0035] The groove 1101 provides a suitable placement space for the screen 13. The screen 13 is laid in the groove 1101, and the screen 13 can be firmly fixed on the sliding frame 11 through the effect of the compression structure.

[0036] When the screen 13 needs to be replaced, the limit of the sliding frame 11 is released by the limiter, and the sliding frame 11 is pulled outward to remove the sliding frame 11 from the rotating frame 8. The pressing structure will automatically release the pressing state of the screen 13, and the user can replace the screen 13 on the sliding frame 11. Compared with the traditional replacement method, there is no need to disassemble multiple parts or perform complicated operations, which greatly reduces the difficulty and time consumption of replacement and improves the replacement efficiency.

[0037] After replacing the screen 13, the sliding frame 11 is reinserted into the rotating frame 8 and the limit of the limiter is restored, and the pressing structure automatically presses and fixes the screen 13. This automatic pressing method can ensure that the screen 13 is firmly fixed on the sliding frame 11, prevent the screen 13 from shifting or falling off due to vibration or impact during use, and ensure the stability and reliability of the screen 13.

[0038] Specifically, Figure 4 and Figure 5 As shown, the driving member includes a rotary arm 9 rotatably connected to the outside of the docking frame 7 and coaxially fixed with the rotary frame 8. A telescopic mechanism 10 is rotatably installed on the outer end of the spreading nozzle 6. The output end of the telescopic mechanism 10 is rotatably connected to the rotary arm 9 through a frame rod.

[0039] The telescopic mechanism 10 can be an existing pneumatic cylinder, hydraulic cylinder or electric push rod, etc., and its telescopic motion is transmitted to the swing arm 9 through the frame rod, thereby driving the swing arm 9 and the swing frame 8 to swing. This linkage design enables the linear motion of the telescopic mechanism 10 to be effectively converted into the swing motion of the swing frame 8. Through the reciprocating telescopic mechanism 10, the swing frame 8 is controlled to swing back and forth, thereby cleaning the impurities on the screen 13.

[0040] Specifically, Figure 5-Figure 7As shown, the clamping structure includes two pressing arms 14 rotatably connected to the side walls of the groove 1101, a rotary rod 15 rotatably connected to the sliding frame 11, and a component for controlling the rotation of the rotary rod 15. The sliding frame 11 is rotatably connected to a gear 16 coaxially fixed with the rotary rod 15, and the side walls of the pressing arms 14 are formed with meshing teeth 1401 that engage with the gear 16.

[0041] The pressing arm 14 is a bent structure, and when it rotates to a horizontal state, the top and side of the screen 13 are pressed tightly in the groove 1101. When the rotating rod 15 rotates, the gear 16 coaxially fixed with the rotating rod 15 will drive the pressing arm 14 to rotate through the meshing action with the gear 1401.

[0042] The component for controlling the rotation of the rotary rod 15 includes a rotary sleeve 18 rotatably connected to the sliding frame 11, a bracket 17 is fixedly provided on the side wall of the rotary rod 15, and a sliding groove 1801 is formed on the side wall of the rotary sleeve 18 for cooperating with the bracket 17 to slide through, and an arc groove 1102 is formed in the sliding frame 11 for cooperating with the bracket 17 to slide, and a compression spring 19 for acting on the bracket 17 is arranged in the arc groove 1102, and the length of the sliding groove 1801 is greater than the length of the arc groove 1102.

[0043] A handle 22 is disposed on the outer side of the sliding frame 11 , and a slide bar 20 is fixedly disposed on the handle 22 and is slidably embedded in the rotary sleeve 18 , and the slide bar 20 is slidably matched with the rotary sleeve 18 through a spline.

[0044] When it is necessary to pull the sliding frame 11 out of the rotary frame 8, first press the handle 22 so that the handle 22 is close to the rotary frame 8, and then the horizontally distributed handle 22 is rotated to a vertical state, so that the handle 22 drives the rotary sleeve 18 to rotate synchronously through the spline. At this time, the inner wall of the slide groove 1801 will release the resistance state of the bracket 17, and because the pressure arm 14 is resisted by the rotary frame 8, it is still in a state of pressing the screen 13. Then the user pulls the vertical handle 22 to pull the sliding frame 11 outward until the rotary frame 8 releases the resistance of the pressure arm 14, and the bracket 17 will drive the rotary rod 15 to rotate under the action of the compression spring 19, so that the pressure arm 14 is rotated and lifted under the meshing action of the gear 16, and the pressing state of the screen 13 is released.

[0045] Specifically, Figure 6 and Figure 7 As shown, the limiter includes a magnetic block 21 fixed at the opposite end of the slide bar 20 and the rotating rod 15, and the two magnetic blocks 21 repel each other with the same poles, and a positioning frame 801 is fixed at the side end of the rotating frame 8 to fit the handle 22. The positioning frame 801 is a two-section bending structure, and the bending portion formed by it is used to fit the handle 22 to be embedded.

[0046] After the replacement of the screen 13 is completed, the handle 22 is turned to restore it to a horizontal state. During this process, the inner wall of the slide groove 1801 will push the bracket 17 to rotate and reset the rotary rod 15, thereby causing the pressing arm 14 to press the screen 13. Subsequently, the sliding frame 11 is pushed into the rotary frame 8. When the handle 22 is close to the positioning frame 801, the handle 22 is turned to be offset from the positioning frame 801 first, and then the handle 22 is pressed inwardly, so that the slide bar 20 fixed with the handle 22 overcomes the repulsive force of the magnetic block 21 and slides inwardly along the rotary sleeve 18. Until the handle 22 moves to the gap formed by the positioning frame 801 and the rotary frame 8, the handle 22 is turned to a horizontal state to pass through the gap, and finally the handle 22 is released, so that the slide bar 20 drives the handle 22 to be embedded in the bending part of the positioning frame 801 under the repulsive force of the magnetic block 21, and the locking of the sliding frame 11 is completed.

[0047] Specifically, Figure 2 , Figure 4 and Figure 5 As shown, the sliding frame 11 is fixedly provided with a blocking bar 12 for limiting its sliding range relative to the rotating frame 8, an open groove is formed on the side of the spreading nozzle 6, and an arc-shaped baffle 23 is fixedly provided at the bottom of the rotating frame 8 to match the open groove for shielding.

[0048] The stopper bar 12 fixed on the sliding frame 11 can limit the sliding range relative to the rotating frame 8. When the sliding frame 11 slides in the docking frame 7, the stopper bar 12 will contact the inner wall of the rotating frame 8 or the corresponding part of the docking frame 7, thereby preventing the sliding frame 11 from sliding further. This design can prevent the sliding frame 11 from sliding excessively and separating from the rotating frame 8 or the docking frame 7, and ensure that the sliding frame 11 moves stably within a set range.

[0049] When the rotary frame 8 swings, the arc baffle 23 can cover or expose the opening slot, thereby controlling the opening state of the side of the spreading nozzle 6. When the spreading nozzle 6 is spreading materials, the rotary frame 8 rotates to a horizontal state, and the arc baffle 23 fixed at the bottom of the rotary frame 8 blocks the opening slot on the side of the spreading nozzle 6, so that the material is sprinkled into the bowl body 35 through the bottom opening of the spreading nozzle 6. When it is necessary to clean the impurities on the screen 13, as the rotary frame 8 swings back and forth, the arc baffle 23 releases the blocking state of the opening slot, and the impurities escape outward through the opening slot.

[0050] Two frame plates 24 are fixedly provided at the outer end of the spreading nozzle 6, and the inner sides of the two frame plates 24 are rotatably connected with a torsion plate 25. The torsion plate 25 and the two frame plates 24 form a storage bin. The material intercepted by the screen 13 falls into the storage bin through the open groove. A shaft rod coaxially fixed with the torsion plate 25 is rotatably connected in the frame plate 24, and a vortex spring 26 that abuts against the shaft rod in an annular direction is provided on the frame plate 24.

[0051] The twist plate 25 and the two frame plates 24 form a storage bin, which provides a space for collecting and temporarily storing impurities trapped by the screen 13. When impurities fall into the storage bin through the opening slot, they can be temporarily stored to prevent the materials from being directly scattered outside the equipment or in the production environment.

[0052] The function of the vortex spring 26 is to provide a restoring force for the torsion plate 25. When the user turns the torsion plate 25, the vortex spring 26 will accumulate energy, and the bottom of the torsion plate 25 will open relative to the material spreading nozzle 6, so that the user can collect the materials temporarily stored in the storage bin. When the user releases the torsion plate 25, the shaft rod drives the torsion plate 25 to automatically reset under the action of the vortex spring 26.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
